It's really hard to understand it.
Try to start from this:

     location = / {
         ...
     }

     location = /ajax.php {
         ...
     }

     location ~ ^/post/([0-9]+)$ {
         ...
     }

     # etc

     # fallback
     location ~ / {
         alias  /path/to/splinder_404.html;
     }
